ESP8285N08

RF Transceiver ICS Overview

The ESP8285N08 is an RF System on a Chip (SoC) manufactured by Espressif Systems, integrating a RISC core with 1 MB SPI Flash. It operates within the 2.4 GHz to 2.4835 GHz frequency range, supporting a maximum data rate of 72.2 Mbps and delivering up to 19 dBm output power. The device functions on a supply voltage between 2.7 V and 3.6 V, with receive current at 73 mA and transmit current at 197 mA. It features a sensitivity of -70 dBm and includes interfaces such as I2C, I2S, SDIO, SPI, UART, and WiFi. Housed in a QFN-32 package measuring 5 mm x 5 mm x 0.85 mm, it supports an operating temperature range from -40°C to +85°C.

RF Transceiver ICS Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific N08 suffix indicates the integrated 1MB SPI Flash variant. Check for RoHS compliance documentation. Note that lifecycle status may vary by region; confirm availability before finalizing designs. Ensure ESD handling procedures are followed during assembly due to moisture sensitivity classification.

RF Transceiver ICS Selection Notes

Select this SoC when a combined microcontroller and Wi-Fi radio is required to minimize board space. It is suitable for applications needing moderate data throughput and integrated storage. Consider thermal management requirements given the operating temperature range. Evaluate interface compatibility with existing host systems if used in a slave configuration. Verify power supply constraints align with the specified voltage and current profiles.

RF Transceiver ICS Part Context

The ESP8285N08 belongs to the ESP8285 family of low-power Wi-Fi SoCs from Espressif Systems. It is designed to provide a complete wireless solution with minimal external components. The N08 designation typically refers to the version with integrated flash memory, distinguishing it from variants without onboard storage. This integration simplifies PCB layout and reduces overall system cost compared to discrete solutions.
